John B. Callahan (businessman)

John B. Callahan (1937-2 August 1982) was a Boston business consultant who was murdered on the orders of Whitey Bulger in 1982.

Biography
John B. Callahan was born in Medford, Massachusetts in 1937, and he earned a business degree at Boston College before working for the Ernst & Ernst and Arthur Andersen & Co accounting firms, as well as for the First National Bank of Boston as a consultant. In 1974, he became president of World Jai Alai, but he left office two years later after Connecticut authorities began to investigate his links to organized crime; police had spotted him fraternizing with Whitey Bulger and members of the Winter Hill Gang. In 1978, he helped arrange the sale of World Jai Alai to Roger Wheeler, who began to launch his own investigation into an embezzlement scheme by Bulger and Callahan. Callahan and Bulger had Wheeler murdered in 1981, and, in May 1982, Edward Brian Halloran was murdered alongside an innocent bystander after he cooperated with the FBI in its investigation into Wheeler's murder.

Death
The FBI then sought to locate Callahan for questioning about the murders, and corrupt FBI agent John Connolly told Bulger's lieutenant Stephen Flemmi that Callahan could be a weak link and implicate them in Wheeler's murder. Callahan was lured to Miami, Florida by Johnny Martorano, who murdered him. On 2 August 1982, Callahan's bullet-ridden body was found stuffed in the trunk of his Cadillac in a parking lot at the Miami International Airport.
